Bypass systems reduce inspection likelihood

B&D Transport owner-operator Brad Lambert uses the PrePass weigh-station bypassing system in his 2003 Freightliner Century at a cost of $13.50 a month, discounted via his Owner-Operator Independent Drivers Association membership. “I don’t get pulled into the scale houses most of the time,” he says.

For carriers with good Compliance Safety Accountability scores, and consequently with no pressing need to log clean inspections, any weigh station bypassing service “will offer an immediate reduction in inspections,” says Brian Mofford, a representative of bypass service Drivewyze.

That scenario has become increasingly common, and 2012 was no exception. PrePass coverage across the nation got a boost with the addition of Texas and Kentucky weigh stations to its now-31-state system. The majority of the contiguous states now are covered by the service.

Sgt. Kelly Anderson of the Kentucky State Police paid witness to the efficacy of PrePass for carriers looking to stay out of the weigh stations in January. Before Kentucky adopted the widely-used system, Anderson’s station typically might see three trucks an hour getting bypassed via the Norpass system. Now that hourly rate is in the hundreds, which means Anderson gets the benefit of a closer look at far fewer trucks.

Drivewyze, a competing service, launched last fall and quickly is coming available at fixed sites; at press time, it was available in 15 total states, with “a state every month” planned for the year, says Mofford. Drivewyze also will become a standard feature of officers’ mobile stations to allow some bypassing in those areas.

“We look at it as a way for those with good inspections to save time and money without having to go on the mainline,” he adds. “Fifty percent of the time, the others can avoid it too” if they want. Many owner-operators and small carriers will register ISS scores in the 50-75 range since the ISS algorithm prioritizes carriers with little to no data in the system for “optional” inspection.

PrePass works in a similar fashion, with below-90 ISS-score carriers and some state exceptions seeing a 95 percent bypass rate. As scores move higher, pull-in rates follow.

California, ranking second in Overdrive‘s rating of inspection intensity, is a notable exception. If your ISS score gets to 75, you may as well turn off the PrePass transponder. The system there pulls in all trucks at 75 or above.

A CCJ poll of fleet management readers showed that smaller carriers generally were less likely than large ones to use weigh-station bypassing. Among fleets with more than 100 power units, 84 percent reported using some kind of bypass system, while 66 percent of smaller carriers reported use. Those rates are reflected in other data. Small fleets receive far more inspections per truck than do the largest fleets.
